Webhook retry mechanism

Hi,

It this ticket,

https://ww.wp.xz.cn/support/topic/webhooks-for-old-orders-fired-now/

Gerhard says:

Also since WooCommerce 3.5 we now use the new WC_Queue class for delivering Webhooks which has a retry for failed events, so it could be a combination of this and the traffic causing old webhooks to retry much later and then finally being delivered.

I can’t see any documentation, reference or code for this retry mechanism.

Can we verify it exists? And if it does, can I get more info about it?

Thanks,
Asaf
